Toni! whom it may concern:

Be it known that l, ALLEN l). limitan, a citizen of the United States,residing at Tupelo, in the county of Lee and State of Mississippi, haveinvented a new and useful Attachment for Print-ingij-Presses, of whichthe i'ollowing is a specification.

This invention has reference to improve- Whether ot the cylinder andplaten or web type, and the object of" the invention is to convert suoliprintingl presses into multicolei' printing' presses. ,1, ln accordancewith. the present invention there are provided inking' units which. areremovable and interchangeable, While at the same time vprovision is madefor positively driving` the inking rollers so that therel may be noslipping. Furthermore, in accordance with. the present inventionprovision is made whereby colors may he printed as closely together asdesired, or may even be made to overlap and blend.

in the practical embodiment of the present invention there is used asingle supplementalA cylinder as wide as the surface to be printed,

and as many inking units are employed as may be necessary for the numoerand locas,

tion of colors desired. Furthermore, there isno danger ot unevenprinting because ot the spring oi the shaft carryingT severalsupplemental cylinders, as might he the were a number of separate sup[lemental cylinders used.

In accordance with the present invention there is provided asupplemental imprinting cylinder receiving` motion from the mainprinting press, and geared to the shaft carrying the supplementalcylinder are other shafts, also thereby being positively driven. Theselast-named shafts each carry inking rollers which may be adjustedlongitudinally :upon said shaft, but are keyed thereto for positive`rotation. In conjunction with the saidvlnklng rollers are inking unitswhich may be removed at w1ll and are interchangeablyused in connectionWith any one of the inking rollers. Each inlring unit comprises asuitable reservoir inwhich there dips a positively driven transferroller for the ink and suitable other transfer rollers are provided fordelivering the ink to the imprinting` surface on the supplementalcylinder. Each nking'unit includes, also, a means for impart' ing to oneof the transfer rollers not only a ,terrii'ig the ink presses. a

movement of rotation but a movement in the line of the axis et Vsaidroller, so that the ink is properly spread when ted to the rollers'transdirectly to the imprinting The invention will be best understoodfrom a consideration of the following detail description takeninconnection with the accompanying drawings forming a part ot' thespeciiication, in which draivings,-'

Figure l is a plan view of a number of ink ing' units in operativerelation one to the otherand also showing some of the coacting parts.Fig. 2 is an end view of the structure shown in Fig. 1 and also showingtheportion of the supplemental cylinder. Fig. 3 is a section on the lineA-B of Fig. l. Fig. et is a longitudinal section of one of the inkingunits on the line C-D of Fig. 1. Fig. 5 is a plan view ot two juxtaposedinlringl units,

with some parte shown in section and some parts omitted. Fig. G isasectional View, on a small scale. to show the manner of' avoiding)rinterference betweenthe paper latches, on the main oyiinder, and thesupplemental cylinder.

lelore entering into ade'tail vdescription of the present .invention itmay ibewell'to state that the invention relates to'an attachment foriulticolor printing, which is as Well adapted to thel cylinder andplaten press as to a web press' and may be used in connection witheither type of press. l

.iti Fig. there is shown thev cylinder 1, of acylinder and platen press,and in operative relation to this. cylinder is shown another cylindeiWhicli constitutes the supplemental cylinder-ci' the present invention.As shown in Fig'. 6 and also in Fig. 2, Vit Will be seen that thesupplemental cylinder 2 is mounted upon a shatt, which, as shown in Fig.2, has suitable bearings 4 inthe framework ot' the press. In the presentinvention the cylinder 2 is as wide as the surfaces to be imprinted,Whether said surface be in the form of sheets of paper or of acontinuous web.

. Mounted in suitable hearings 5 attached to the main frame of the pressare shafts and 7. The shaft 3 carries a gear wheel 8 which is in meshWitli pinions 9 and 1() on the shafts 6 and 7 ,.respectively, so thatwhen 'the shaft 3 is driven the two shafts '6 and 7 are driven likewisebut Iat a higher rate of speed. p

- Thepinking rollers 11l constitute each a 'part of unit, but not theremov-v The lastnamed part of the inking unit'is composed of a suitlable frame and ink reservoir, transfer rollers and another rollercoacting with the Sist-named" roller. 4The frame of the inking unitconsists of two side plates 1 6 and 17 secured together in spacedrelation parallel one tot-he other by suitablebolts 18 and another bolt19, to'which reference vvillv presently be made. j j

Mounted in slots in the side plates '16 3Q'- and 7 of the frame of theinking unit is a 4shaft ."2-1 of af composition inking .roller 22, thelatterbeing', so tive relation to the rinting surface. on the cylinder 2when the mking unit is in o era'' tive relation tothe cylinder The bo t19 between the two plates 16' and' 17 is 4made :square and receives ahook 23, the square bolt serving to hold the hook in an suitable poitinof adjustment. Thehoo 23 is located pleferabl midway between the twoplates 16 and`17, 'utit may be, located nearer one ,plate than theother, if so desired. l

ocated as to .be in operaer inconnection with the roller 24." Pivotayconnected to the side plate 16 is 28. The lever 27 with the part ofltl'i'efapaper to colors, and thenthe inkingl units. are hung* 22.` Theshaft30 of the roller 31 projects through the lever 27 and -therecarries a grooved hub 35. .The shaft or journal-33 projects through ltheside plate 16and there carries a smaller hub 36, also grooved like thehub 35.

One journal 37 of the roller 24 projects through the plate .16 and therecarries a disk- 38', on diametrically opposite points of which areformed teeth or tappets 39. The disk 38 is also formed onopposite facesat diametrically opposite points With cam projections 40. Mounted inpivotal bearings 41v on the plate 16 is a lever 42 having one endprovided With a pin 43 enteringgthe groove in the hub 36, and on theopposite side'of the pivot 41 this lever is provided with another gip 44entering the groove in the hub 35. yond the pin A44 the lever 42 isformed into a fork 46 straddling the ldisk 38 and-having thev end of thefork'in o erative relation to the cam members l40. l he roller 24 hasits other journal 47 projecting through the plate 17 and there carries aWorm Wheel 48 in engagement with a Worm 49 on a shaft 50 having journalbearings on the plate, and at the other end provided With the bevelpinion 51 in engagement with a bevel'gear 52 on the corresponding end ofthe hub 12 of the roller 11. The hub 12 back ofthe gear 5 2 is formedwith a circumferential groove 53, and on the otherv end with anextension 54.

At the end remote from the hook 23, each plate 16 and 17 is out out 'tostraddle the hub l 12in the groove 53 and extension 54, respectively.Fast to'each plate 16 andr17^by a link 55 is a latch member 56 also cutout' 'to partly encircle the hub 12 in the groove 53 or extension 5.4,-as the case lmay be. hook 57 pivotally secured to one of the bolts 318is provided for fastening the latch inemin 58 at the correber .56 bymeans of a..

member over which sponding end of the latc the hook 574 engages.

The supplemental cylinder 2 is in operative relation to another cylinder5 9'.whicl1 may re resent either the. cylinder of a cylinder'an platenpress or a 'corresponding cyl.- inder of'a web press.

l Now,letit be supposedthat it is deslrable to imprint incolors upon thepage .ofa newspaper in spaces lelft for the pur ose.` The proper.electrotypes arevfastene upon the cylinder 2in position toregister-'with the blank spaces on the imprinted pa er. lAdjacent`to thecylinder-2 and para lel therewith is a rod v60 suitably supported fromthev framework of .the machine. This rod receives the hook 23 fof theinking unit, while the latchend -of ytheunit is engaged about the, .hubl2 ofthe corresponding inklng rollers 11;, v

The inking rollersl 1 1'. are brougtlit into registen upon the rod 60''andflatchedto Vthe corree imprinted in..

erases sponding inking rollers 1l. lnk of the desired color is placed inthe ink reservoir 25 and different colors may be placed in the severaldiderent reservoirs. if, non', the printing of the paper be assumed tobe progressing the operation of, the inking unit is as follows: Theshafts 6 and 7 are positively driven and the rollers 11 participate inthis movement. However, only those inliing rollers 11 `which receive inkfrom an inking unit cause the imprinting suriace on the roller oicylinder 2 to imprint-on the pa ier. 'lhe pos'ttve rotation of theshafts 6 and 7 impart co istant movement to the rollers La through theshaft 50 andthe Worin gears 49 and 48. l he lever 27' `is provided with'an angle armt1 terminating ina -roller 62 in the path of the teeth or`tappet 39. \.`hen the roller 24 is set in ro,- tation, the teeth 39ente-r under the roller 62 and cause the lever 27 to rock on its pivotto bring the roller 81 into contact with the roller 2 4, andthe roller31 thereby receives a charge of ink. la hen the tooth has passed fromunder the rollerv 62 the roller 31 returns into engagement with theroller 34, and the latter receives the ink carried by the roller 31. Thelever 42 is in the meantime being rocked vabout its pivot by theengagement of the cam sol 40 With the forli end 46 of said lever 42, and

this lever imparts to therollers ,31 and 34 Aa.v

reciprocatory movement in the direction oi' the axis o't' these rollers.-The inl: is .thereby evenly spread upon the rollers 13 and and by thelatter is transferred to the imprinting surface upon the cylinder 2, tohc thereby in turn transferred to the spaces lett iii the main imprintupon the paper.

ll' it be desired to print the same matter in dii'lerent colors atdifferent times, then 1t 1s only necessary to unlatch the unitcontaining the color not Wanted and to replace it vwith another inkingunit having the color desired. Under such cireuinstances, it is onlynecessary to clean the inliing roller 13 and the electrotypc 'from whichthe impression is made.

Suppose it be desirable to print the same matter in two colors, thentivo inhing units may be made to overlap, as sho'ivn at the right handof Fig. l., and one inking unit may carry one color and the other inkingunit may carry the other color, and both deposit ink upon the sameimprinting suriace. lt is also possible to malte the colors actuallyoverlap and thereby blend to any desired extent.

Ordinarily, the hooks 23 are arranged. central to the inking unit, butthey iay be arranged a little to one side of the center so that twoinking units on opposite sides of the rod 60 may be brought into exactalinement, and in such case tvfo dil'l'erent colors may be made to blendentirely over Athe inked imprinting surface and thereby produce another.color caused by the blending of the two colors supplied by the unit.

It vvill be observed that the only adjust,-V

ment or register' needed .is-provided for bythe inking rollers 11, whichmay be readily adjusted into register with the imprinting' surfaces.'lhe removable portion ot' 'the units are freely interchangeable onewith the other and the ipliing rollers 11 determine the registering oflthe removable part of the inking nuit with the matt-er tobe inked,y

It sometimes happens when the electrotypes are thin that thesupplen'iental cylinder will engage the paperlatches indicated at G3 onthe main cylinder' l." To avoid this the electro-type maybe cut out, asindicated at G4, Fig. 6,. and may also be out out as indicated at forthe spaces between pages.
